Ancient rocks reveal continent-breaking critical mineral origins
Ancient rocks reveal continent-breaking critical mineral origins Rare rocks buried deep beneath central Australia have revealed the origins of one of the world’s most promising new deposits of niobium. The Curtin University-led study found the newly discovered niobium-rich carbonatites were emplaced more than 800 million years ago, rising from deep within the Earth through pre-existing fault zones during a tectonic rifting event that ultimately tore apart the supercontinent Rodinia. Lead author Dr Maximilian Dröllner, from the Timescales of Mineral Systems Group within Curtin’s Frontier Institute for Geoscience Solutions and the University of Göttingen, says the findings shed new light on how rare, metal-rich magmas...
